I've heard from relatives that it is the same thing in Hong Kong. Last time I talked to them they said it has been quite difficult so far. I'm not sure if they have had any training to prepare for this at all or if they are just winging it.
Lack of space at home might also be an issue. Hong Kong flats can be pretty small.
Many homes aren’t really suited to WFH, especially regular WFH. They might be noisy during the day, lack space, lack decent network connections, etc...you also can’t really WFH from a quiet public space like a library (not that HK really has those).
